DB2 FOR LUW / DB2FORLUW / B10 - DB2 |
| Problem description: |
A query may return more rows than expected when the following
conditions are satisfied:
- the query has multiple inner joins between column-organized
tables, using equality join predicates
- the same columns from the same tables are repeatedly used in
many of these equality join predicates
- at least one such equality predicate involves a join between
such a column and an expression
The issue is access plan dependent. |
